Improvement in oil-cans



UNITED STATES MICHAEL S. KAVANAGH, OF DETROIT, MICHIGAN.

IMPROVEMENT IN OIL-CANS.

Specification forming part of Letters Patent No. 117,544, dated August1, 1871.

To all whom it may concern:

Be it known that I, MICHAEL S. KAVANAGH, of Detroit, in the county ofWayne and State of Michigan, have invented a new and useful Improvementin Oiling-Cans; and I do declare that the following is a true andaccurate description thereof, reference being had to the accompanyingdrawing and to the letters of reference marked thereon, and being a partof this speciication, in which my invention is shown in perspective,with such parts of the can broken out as are necessa-ry to show theWorking parts.

The nature of this invention relates to an improvement in theconstruction of oiling-cans, so arranged that the ow of oil through thespout is always under the control of the hand, and tha-t it will notlose any of its contents if accidentally overturned.

The invention consists in the mechanism for operating a valve in thespout, while at the saine time it allows of access to the interior ofthe necessary air, the pressure of which forces the oil out of the spoutwhen' desired; also, in a valve which is closed when the implement iselevated in the position shown in the drawing for use, but open at allother times to allow the escape of air from the interior, therebypreventing the expansion of the air in the can,wl1en warmed, fromforcing out the oil; also, in the combination of all the parts, as andfor the purposes more fully hereinafter set forth.

In the accompanying drawing, A represents an oiling-can, provided withthe usual spout, B. In the spout is placed a proper seat, C, to receivethe valve D, which is secured to the top of the rod E, which passesdownward to the bottom of the can, whence it turns upward through thetube F, and terminates in a knob, G. At the bend ofthe rod, near thebottom of the can, the rod engages vwith the bale of a helical spring,H, which is secured to the opposite side of the can. The tube F may beplaced outside the can, as shown, or inside the same, .if preferred. Inthe top of the can is a vent-hole, I, and J' is a valve secured to onearm of the bell-crank K, while the other arm is weighted. Thisbellcrank, with its attachments, is secured to the inner side of the topin such a manner that when the can is standing upon its bottom thevalvedocs not cover the vent-hole; but when in use, and in the position shownin the drawing, the weighted arm of the bell-crank compels the valve toclose the vent. When this is done pressure upon the knob G withdraws thevalve D from its seat, allowing an outiiow of the oil, while thenecessary pressure of air is obtained through the tube F.

What I claim as my invention, and desire to secure by Letters Patent,is-

The combination of the can A, spout B, seat C, valve D, rod E, tube F,spring H, valve J, and bell-crank K, when the several parts areconstructed, arranged, and operated substantially as described andshown, for the purposes setfOrth.
